Abstract
Fundamental properties of micro supercooling flow were demonstrated. We found that the freezing temperature of water depends on surface properties and size. The lowest freezing temperature was observed as -28 °C in the 70-μm-wide microchannel modified with hydrophobic group. Then, we confirmed the freezing temperature was independent of flow. Furthermore, we found micro supercooling flow can be realized for organic solvents. © 2006 Society for Chemistry and Micro-Nano Systems.
